Fishermen catch fish using nets, poles, and lines. The fish are then processed - graded, cleaned, cut, and packaged. For fish not sold fresh, other processing methods are used like smoking, drying, or flash freezing. Smoked fish undergoes salting, cold smoking, cooling, packaging, and storage. Dried fish has water removed to prevent bacterial growth. Flash frozen fish like salmon and corn are frozen very quickly below zero degrees. The processed seafood is transported in refrigerated trucks to fish markets where it is auctioned. Local fishmongers then sell the fish to customers to be cooked and served.
